The housing` (1) for my carbonatorrests onabase (2)Y and'comprises anelevated bot.

Theieylindrical housing .iscovered bymeanfs` of a suitable lid also preferably'illed withinsulatingmateriial asv shownat (11) a knob (12) :facilitating thehandling ofy the` same.vr f

In this: housing issupported concentric with the' same a cylinder` (13)engaging. a groove. (14:){inmthe'bottom'ol1 the.y housing and' agroove..(1(5f)A in a top plate (17 so as to form aV gasftight chamber(18). The upper: plate (17) is pressed'upon the vrWall (13) -aird'thelatter upon theA bottom plate byfmeans of nuts; V(15) threadedly'-engag-ingrrodsi. (2O)V rising from the bottom on'v tthe ,outsidevoit'. the cylindrical Wall (13)A and extending through kpert'orations inthe upper plate. k)Vater may be vadmitted Aintov thisjchamber througha'pipe' (19) connecting with any suitablefsource of Water, as for,

instance tlie city Water: ipes and provided` ber (18') serves/as adrainpipe.

Gasis admitted rome anysuitabl-'e lsupply through-the pipe by theiiollo'vvingfarrangement.;- .KA .sleeve (24)- threadedly en gagesth'eibottom plate of'v the housing at itsr center 'and extends slightlyabove the bottomv member`` (3)1 and through a: considerable distance'below the latter member.4 ltsV lower end which is enlarged incrosstsection isf threaded internally as shown at (26) and is adapted toreceive the upper reduced end of yav nipple I having a nozzle'(28) ofvery small cross sectionaliarea Whichrlatter threadefdly engages the endof the pipe ('23). 'lhesleeve (24') which is. showirwinfdetail' inFigures 5, G and 7 is adapted to serve as a guide member for the lowerend of the stem (29) extending through the length of the chamber and isprovided with a plurality of internal grooves (31) allowing the gas topass the stem provided the latter is raised suliiciently high to clearthe nozzle (28). The stem is provided in its lower end with a small bodyof rubber (32) which closes the nozzle (28) if the stem is presseddownwardly.

The upper end of the stem (29) is guided byl means of a sleeve (33)disposed in the center of the top plate and is provided near its topwith a collar (34) adapted to be engaged and to be pressed down upon bythe short arms (36) of a plurality of levers (37) pivotally supportedbetween lips (38) extending downwardly from a ring (39) formedintegrally with the sleeve The long arms (41) of the levers bear on thetop surface of a float (42) so that when the float rises the stem (29)is forced downwardly and when the float falls the stem (29) is allowedto rise under the influence of the gas pressure.

The float (42) consists of a large plurality of inverted bells (43), oneof which is shown in detail in Figure 8. Each bell consists of a disc(44) having a flange (46) depending from its outer circumference andhaving a depressed central portion (47) formed by an internal flange(48) and a bottom member (49). The latter has a central perforation (51)and the internal flange (48) is provided with a plurality ofperforations (52) disposed in such a manner that they are below the disc(44) but above the lower eX- tremity of the outer flange (46). T heperforation (51) allows the bell to slidably engage a tube (53) whichlatter is made slidable on the stem (29). Between each two bells isinterposed a spacing member (54) slidable on the tube and provided atits upper end with an enlarged cup (56) adapted to engage the depressedcentral portion of the bell above it whereby all the bells are held inparallel relation. The depressed central portion of the lowermost bellrests on a disc (57) provided with a flange (58) encircling said innerportion. This disc threadedly engages the tube (53) and all the bellsand the spacing members are forced into one. firm unit by means of a nut(GO) threadedly engaging the upper end of the tube The disc is supportedon the sleeve (24) which as previously stated extends sightly above thebottom plate of the carbonator. To allow gas to pass between the latterdisc and the sleeve while the float is in its lowermost position lprovide transverse grooves (58) in the latter sleeve as shown in Figures5 and 6.

Carbonated water may leave the chamber through small passages (59) inthe sleeve (33) so as to enter a tube (61) communicating with saidpassages through a port (62) in an embossment (63) to which the tube issecured by means of a union (64). The tube ((31) leads into the exteriorby communicating with a pipe (G6) supported in a bracket (67) extendingfrom the top plate (17 `Any suitable faucet may be connected to thelatter pipe for withdrawing the carbonated water.

The operation of the device may be describet as follows: )Vater isadmitted under pressure through the pipe (19) and the pipe is connectedto a suitable source of carbon dioxide under pressure. Normally thepressure of the gas exceeds that of the water. lVhen there is neitherwater nor gas in the chamber (18) the float will descend to itslowermost position as shown in Figure 1. The gas being` under pressurewill lift the rod suiliciently high to allow the gas to pass the samethrough the grooves (31) in the sleeve (24) at the same time the waterrushes into the chamber. Both water and gas will first iill thelowermost bell, the gas rising and occupying the upper space while thewater will occupy the lower space. A thin layer of gas will be entrappedin the valve while a surplus amount will follow the course of the waterand rise with the same through the holes (52) to lill the space of thenext bell. In a similar manner one bell will be filled after the otherand a thin layer of gas will be trapped in each bell so as to engage alarge area of water which will cause the gas to be readily absorbed bythe water. The buoyant effect of the water on the gas entrapped underthe bells causes the float to rise and lifts the long arms (41) of thelevers (37) thereby depressing the collar (34) on the stem (29) andforcing the latter downwardly whereby the nozzle (28) is closed. Therebythe supply of gas is shut off and the valve for the gas supply is notopened until the gas entrapped under the bells is absorbed by the water.1t will be seen that in this manner a thorough absorption of the gas bythe water is obtained and that at the same time the gas supply regulatesitself automatically in accordance. with predetermined rules.

I claim i 1. In means for charging a liquid with a gas, a chamber, meansfor admitting the liquid into the same, means for admitting the gas intothe chamber and a float control for the gas including a plurality ofinverted bells mounted above one another in spaced relation, each beingadapted to trap a layer of gas, and having a downwardly extendingcentral flange with an outlet therein disposed intermediately of the topof the bell and the lower extremity of the bell, said outlet beingadapted to allow a surplus of gas to escape into the neXt higher bell.

2. In means for charging'a liquid -with a gas, a chamber, means foradmitting the liquid into the. same, a central gas intake in the bottom,a vertical stem adapted to yclose the gas intake and a ioat slidable onthe stem having means associated therewith for depressing the stem so asto close the gas intake when the float rises, the float com prising aplurality of bells arranged above one another in' spaced relationadapted to trap layers of gas within 'the liquid.

8. In means for charging a liquid with a gas, a chamber, means foradmitting the liquid into the same, a central gas intake in the bottom,a vertical stem adapted to close the gas intake and a float slidable onthe stemhaving means associated therewith for depressing the stem so asto close the gas intake when the float rises, the float comprising aplurality of bells arranged above one another in spaced relation adaptedto trap layers of gas within the liquid, and having a downwardlyextending central iiange with an outlet therein disposed intermediate ofthe top member and the lower extremity of lthe bell, said outlet beingadapted to allow a surplus of gas to escape into the next higher bell.

t. In means for charging a liquid with a gas,ra chamber, means allowingthe liquid and the gas to enter the chamber through the bottom thereofwith the pressure of the gas rate the water and the gas in' successivelayers in the chamber for securing a better absorption of the gas.
